Spark plugs are a service item on most bikes. The VFR needed to be partially dismantled to even have sight of the things. Valve clearances on boxers could be done, even by me, in half an hour. On the VFR, you needed to remove fairing panels, fuel tank, radiator, and purchase Honda service tool 07GMA-ML70100. Similarly, carb balancing was a breeze on the BMW, but best left to grown-ups on the VFR. I had a bit of an issue with water in the fuel tank on the BMW. It was a matter of moments to pop off the float bowls, pour the fuel back into the tank and discard the dirty water in the bottom of the bowl. A similar problem on the VFR would have required a recovery truck. The barrel, piston and cylinder head replacement was due to me exceeding the recommended service interval on the exhaust valve (60K). Replacing the damaged items with secondhand bits from Motorworks cost me less than, say, replacing a cam belt on your average modern car would have. On the VFR, a dropped valve would have seen the brute parted out. The barrel, piston and cylinder head on the BMW are not actually service items themselves.

Yep, every 16,000 miles usually. That's usually when the airbox etc needs to come off to do carb balancing and valve clearances anyway so it's no big deal to do plugs at the same time. If my bike was in constant need of new plugs I'd be getting shot of it. -- Lozzo Versys 650 Tourer, CBR600F-W racebike in the making, TS250C, RD400F (somewhere)

Most of the previous owners of SOBs I have owned have been pervious. |
